It only costs a few lines of trivial code to fit the distribution logic. Does it really require a new (and mostly identical) pattern?

In that case I suggest using the format used in WGtoSG. (use some template naming).

```
using WgToSgVectorConstantMaskOp = WgToSgVectorMaskOp<vector::ConstantMaskOp>;
using WgToSgVectorCreateMaskOp = WgToSgVectorMaskOp<vector::CreateMaskOp>;
```
